Ain't helping that the guy who "discovered" this claims it is some kind of "YouTube wormhole" you supposedly fall into and never ever can escape from. Even tho he pretty much did everything to make the results come out as they did (fresh YouTube account, using a VPN, looking up content that's already considered as "soft-core" for many users).
But the reality is that these videos show nothing illegal or really that out of the ordinary. The fact that some people derive sexual pleasure from them, is something that can never be stopped unless you introduce something akin to mass-scale thought/mind-control.
Because before it was YouTube videos or the Internet it was plain old children underwear catalogs printed on paper and without these, or YouTube videos, those people would just do a Google picture search of "childrens underwear" and get unlimited pictures of children in equally revealing poses as in those YouTube videos.
What to do about that? How to "fix" any of this? Particularly in an age where becoming a "YouTube personality/influencer" is increasingly peddled as some kind of viable choice of occupation for younger people and even children [0]?
